Which options did you use for configure?

On Lenny you should try usind hal instead of udev. But this is only 
resonsible for detecting removable devices. As a fallback scanbd can be 
signaled (using some udev-rule, e.g.), please check the docu.

First of all scanbd doesn't detect any scanner. There may be various 
reasons. But most likely scanbd uses a wrong dll.conf.

Did you
export SANE_CONFIG_DIR=/usr/local/etc/scanbd ?

please show your configs:

/etc/sane/dll.conf
/usr/local/sbin/scanbd/dll.conf
/usr/local/etc/scanbd/scanbd.conf

and show the env-vars for the user starting the scanbd (root).
